We have a guy that comes out to mow and edge once a week. He charges us almost nothing...kind of a friend and family rate. I wasn't home today and got a call that this week, instead of edging, he sprayed the dandelions. We had the discussion at the beginning that we did not want fertilizer or other sprays. Sure, our yard is messier, but the chickens are so happy to be fed dandelion greens. And, although I don't tell other people what to do with their property, I've always kept mine spray free as that is congruent with my values. The girls were relatively safe in their run today, but I'm concerned about overspray etc. Anyone know the half life of some of this stuff? When those areas might be safe again? Thanks.
